This invention is for improvements in or lapping portions of the cigarette paper or the continuous rod may be sealed together in an extremely efficient manner.

The present invention consists of a heat ing device for use on a cigarette making machine of the continuous rod type, wherein a heating element comprises a series of projecting teeth or the like, arranged to extend into a series of corresponding transver slots formed in the folder of the rod forming mechanism so as to bear upon the overlapping edges of the cigarette paper.

The invention is more particularly described with reference to the accompanying drawings, in which Fig. 1 illustrates in side elevation a heater constructed according to the present invention.

Fig. 2 is an end elevation of Fig. 1.

Fig. 3 is a section on the line A.A of a pin and slotconnection mounted betweenthe two heaters illustrated in Fig. 1.

Fig. 4 illustrates the heating element of one of the heating devices illustrated 'in Fig. 1.

Fig. 5 is an end view of? Fig. 4c.

nag. (3 is a part plan of the folder illu trated in Fig. 1.

Figs. 7 and 8 are sections on the lines -B and C-C of the folders illustrated in Fig. 6, and I v Fig. 9 is an elevation of the folder 1llus-- trated in Fig. 6.

Referring to the drawings there is illustrated an electric heating element which comprises a coil of resistance wire (not shown) and a bar 1 made from a good heat conducting material, such as copper. The

heating element is mounted in a cylindrical casingQ in such a manner that the bar 1 eX- tends beyond the cylindrical surface thereof. The casing 2 is secured by a bolt 3 to an arm 4: which is mounted upon a spindle 5 carried upon a standard 6 supported upon the frame of the cigarette making machine.

The position of the arm may be adjusted by means of an adjusting screw 7 mounted on the arm 4: and adapted to engage with a projection 8 formed on v the standard 6. Secured to the arm 4 is a handle 9 by which the heater may be moved about the axis of the spindle 5 so as either to rest, as illustrated in. Fig. 2, upon the overlapping edges of the paper of a cigarette rod, or be raised into a position out of engagement with the rod.

The bar 1 of the heating element is preterably'provided with a series of projections 1 which are adapted to extend into a series at slots 1 formed in the folder 110i a cigarette making machine, so that when the heater is in engagement with the cigarette rod, the projections 1, together with the portions 1 of the folder which lie between the projections 1*, they maintain the rod in the folded condition and simultaneously apply heat'to the rod as the same is passing through the folder.

The heater which engages with the folder of the rod forming mechanism may be provized with a second heater, the heating rod 12 (Fig. 1) of which is in alignment with th rod 1 of the first heater, and't-he two heaters are arranged end to end so that the cigarette rod heater, without increasing the length of the cigarette making machine.

The first heater is operatively connected to the second heater through the pin and slot mechanism illustrated in Figs. 1 and 3,

gaette rod is subjected to heat over subantially twice the distance of the normal,

whereby the first heater may be moved into and out of engagement with the cigarette rod, without interfering with the second heater, but it is arranged so that when the second heater is moved out of engagement with the rod, a projection 13 on the spindle 14 or thesecond heater enga es with a pin 15 on the spindle o otthe first h ater and automatically moves the first heater out of engagement with the cigarette rod. I

if necessary, the heating element of the first heater may comprise a series of metallic discs spaced apart from one another by heat insulating material and the discs may be arranged so as to extend into the transverse slots 1 in the folder of the rod forming mechanism so that they bearupon the overlapping edges-of the paper of the cigarette rod. The discs may be heated in any desired manor, torexample, by an electric heating element, and may, if necessary, be rotated so as to sweep over the overlapping edges of the paper. of the cigarette rod and act as a cleanser of the overlap as well as a, heater.

Thus it Will be seenthat according to the present invention there is provided means whereby a heating velement may be considerably increased in its length Without increasing the ordinary dimensions of the cigarette making machine.

W'hat I claim as my invention and desire to secure by Le ters Patent is 2'- the combination or" a folder for forming the,

cigarette rod, said .ioider being provided with an aperture in the 'Wall thereof, means for heating said rod, a support for said means whereby the latter may be moved into and out of said aperture, and an adiustable member for limiting the movement of said means into said aperture.

A heating device for use ona cigarette making machine of the continuous rod type which comprises in combination a heating element having a series of projecting teeth formed on the he'ating'suritace thereof, and

the continuous rod type,

a folder for forning the cigarette rod'having a series of corresponding transverse slots arranged to receive the teeth of the heating element so that the same bear on the overlapping et ges of the cigarette paper folded about the rod of tobacco.

LA heating device for use on a cigarette making machine of the continuous rod type which comprises in tombinat-iona heating 'eiementhaving a series of projecting teeth formed on the heating surface thereof, a rod forming mechanism provided with a series of transverse slots arranged toreceive the teeth of the heating element so that the same bear upon the voverlapping edges of the cigarette paper folded about the rod of tobacco a second heating eienient arranged to constitute a con inuation of the heating surface of the first heating element and means operatively connecting said heating elements whereby the first heating element may be moved into and out of engagement with the cigarette rod Without altering the position of the second heating eienie'nt, Whereas the first heating element is automatically moved out of engagement with the rod as the second heating element is moved into an operative position.

In testimony whereof Ihereunto my signature.
